1. Background
The Gensonic employs a process termed “Cavitation”. Micron-size bubbles establish
and grow because of positive and negative pressure waves in a solution. Until the
bubbles reach resonant size, they are continually growing. There is an enormous
amount of energy stored inside the bubbles themselves.
Temperature inside a cavitating bubble can be extremely high, with pressures up to
500 atm. The implosion event, when it occurs near a hard surface, changes the
bubble into a jet about one-tenth of the bubble size, which travels at speeds up to
400km/hr toward the hard surface.
With the combination of pressure, temperature and velocity, the jet frees
contaminants from their bonds with the substrate. Because of the inherently small
size of the jet and the relatively large energy, ultrasonic cleaning has the ability to
reach into small crevices and remove entrapped soils very effectively.
2. General Description
The Gensonic is a manually operated ultrasonic transducer unit for cleaning stencils
used in printing solder pastes and glues.
It can be used either directly on the printer or the stencils can be taken to the
Gensonic stencil cleaning centre.
Screen printed solder pastes tend to compact and trap particles into aperture
corners and lead free solder pastes, that are less dense, tend to demonstrate this
tendency even more.
To clean effectively requires both “chemical” and mechanical agitation. Direct
ultrasonic contact cleaning is the ultimate way to clean SMT stencils with the
minimum amount of cleaning chemistry.
Employing a 40kHz ultrasonic generator, the single transducer head cleans with
great efficiency. However for certain tougher applications, such as partially set glues,
a Gensonic unit with 2 transducer head units should be used.
This cleaning technique requires only minimal amounts of “chemistry” to be used to
reduce environmental impact and cost.
The stencil is placed into the SCC (Stencil Cleaning Centre) frame mounted over a
special foam pad overlain with a disposable paper. At the completion of each
cleaned stencil, simply lift the frame on the supports provided, pull the paper clear,
and cut off.

3. Main Features
The Gensonic unit can be purchased with or without Gensonic SCC. Two different
sizes of SCC are available to choose from (SCC29 = 740x740mm and SCC24 =
584x584mm).
Typical features are listed below:
A cost effective method to use
Uses minimal processing fluids
No risk of stencil damage
Typical 3 minute cleaning cycle
Suitable for both stainless steel & plastic stencils
Cleans solder paste or SMD adhesives
Accepts both foils or framed stencils
4. Safety precaution
Any connection between power sources and transducers should be firmly fixed.
Ensure the unit is connected to the correct supply voltage and is earthed.
The unit should be ground to prevent electrical shock.

6. Operating procedure
Step 1
Unpack your Gensonic unit carefully and place in desired operating location.
Step 2
Plug the foot pedal connector into back of Gensonic as shown. Then place foot
pedal on the floor in desired location for operation.
Step 3
Plug the transducer into the front of the Gensonic. NOTE: ensure the keyway on the
plug is lined up correctly. Push into position and screw clockwise until fully
inserted.
Page 6
Step 4
Plug the mains cable in at the back of the unit.
Step 5
Switch the Gensonic on. When powered, the mains switch will be lit. The red LED
will also be lit to signal the unit is ready to be used.
Step 6
Spray the stencil with cleaning solution before Gensonic use*. NOTE: Do not
operate Gensonic on a dry stencil!
*If you have a Stencil Cleaning Centre, please refer to the operating guide to using
the Gensonic with the SCC before operation below.

Step 7
To operate the Gensonic, press the foot pedal down and hold. You will see the
green LED on the front panel light and you will hear a noise signifying that it is
working. Rotate the transducer on the stencil slowly and you will soon see fantastic
results.
Step 8
Switch off the Gensonic when not in use.
7. Using the Stencil cleaning centre
Page 8
Step 1
Cover the aperture area of the stencil using paper roll provided, and then spray and
dampen the under screen paper.
Step 2
Place stencil into support chase and spray fluid provided over aperture area. After a
few seconds, remove all bulk solder paste in the surface of stencil using paper towel.
Page 9
Step 3
Spray fluid over aperture area again. Move transducer head unit over aperture area
by pressing foot switch.
Step 4
Using the handle, move the SCC platform to the raised position allowing top and
underside drying. All residues are absorbed into the under screen cleaning paper.
